I have run across this question in another thread and I figured I would ask becasue I wanted to use for of these servos in a goldburg extreme. there has been conflict with what futaba and what tower hobbies say about batteries for these servos. futaba says on the box to use nicd batteries only. tower hobbies say you can use NiMh batteries of good enough capacities. what is the verdict on battery power for these servos ?
